I'm consistently impressed with the folks on recruitingblogs. Specifically, the varying philosophies and methodologies that span this blog all pointing to one common goal; client satisfaction. With this in mind I have two questions:
1) What is the value that you, as an external recruiter offer your client - (what do they pay you for?)
2) Do your clients give a hoot where/how you source your candidates? Specifically, if they are impressed by your candidates but not how you sourced them, would they punt on a hiring decision or continue to work with you?
